T all 'L1/71,077.7, it muy con/cern:

Be it known that I, ASA JOLLY, a citizen of the United States, and a resident of Seward, in the county of Stafford and State of Kansas, have invented a new and Improved Disk Cultivator, of which the following is a full, clear, and exact description.

My invention :relates to disk cultivators, and has for its object to provide a drag frame adapted to support a frame upon which disk gangs are mounted, and to adjust said gang frame and disk gangs vertically relatively to the drag frame; to provide means for adjusting the inner ends of the disk gangs vertically and horizontally, and also to provide shields or fenders adapted to travel between the center disks of the gangs. This I accomplish by the means illustrated in the accompanying drawings, in which drawings like characters of reference indicate like parts throughout' the views, and in which Figure 1 is a plan view of a cultivator einbodying my invention; Fig. 2 is a vertical longitudinal section taken on the line 22 of Fig. 1 Fig. 3 is a perspective view of a bracket; and Fig. 4 is a side elevation of a section of a lever having a spring actuated latch engaging a notched segment.

As illustrated in the drawings, a sled is formed having runners 1 preferably made of angle iron and inclined'upward at their forward ends, to which are attached links 31 adaptedl to be connected with a drag chain. Vertical standards l2 are secured to the forward end of said runners and provided on their upper ends with clamping boxes 3 adapted to receive a cross bar 5 which is preferably constructed in the form of a tubular shaft. The cross bar is clamped in position by means of caps 4 which are bolted to the upper end of the standards 2. Similar standards 12 are secured to the real ends of said` runners and provided with clamping boxes similar to the boxes 3 mounted on the forward standards, and provided with caps 4 adapted to clamp a rear cross bar 5aL of greater length than the forward cross bar 5. By means of such construction the runners may be adjusted laterally relatively to each other on the cross bars 5 and 5a. For this purpose the cross bars are made of sufficient length to provide for the widest adjustment desired for the runners. A disk gang frame is mounted upon the rear cross bar 5a and consists of rearwardly extending arms or draft bars 15 connected together by means of a transverse bar 16. A central draft rod or arm 14 is also attached to the cross bar 16, and its forward end is secured to the cross bar 5a.

A bracket 17 is provided with a vertical flange 29 having vertical slots 29a. The flange 29 of the bracket is secured to the cross bar 16 by means of bolts extending through the vertical slots 29a which thereby enable the bracket to be adjustedvertically on the said cross bar. The bracket is also provided with a slot 17 a adapted to receive a bolt 19 which connects together the inner ends of the axles 18 and permits the inner ends of said axles to be adjusted lengthwise of the slot 17 a. The axles 18 are supported on the rear ends of the draft bars 15 which may be inclined inwardly at their rear ends, and are preferably countersunk on both sides of the bar so as to permit the gang axles to be rotated horizontally on the ends of said draw bar without binding therewith. Concavoconvex disks 20 are mounted upon the axles 18, and may be secured to a flange 21":l formed on spacing spools 21 which are adapted to rotate on the axles 18. The outer spools 22 are preferably made shorter than the inner spools, andthe outer ends of the gangs are provided with hubs 23` having annular iianges adapted to'overlap the outer ends of the spools 22, and thereby prevent dirt and other foreign matter from entering between the spools and axle. These hubs may be secured to the ends of the axles 18 by means of set screws or by any other suitable means. Collars 24 are secured to the axles 18 so as to bear against the concave faces of the inner disks and bind the disks and spools together. A rearwardly extending arm 25 is attached at one end to the bracket 17, and provided with apertures 25a adapted to engage a bolt 80 preferably affixed to the bracket 17, by means of which and an engaging nut the arm 25 is secured in position. Circular disks 26 are secured to a connecting shaft 27 which is journaled upon the rear end of the arm 25. These disks or shields 26 may be set in any desired position relatively to the disks 2O by adjusting the bolt 30 in the arm 25 so as to protect the rows of plants from being too heavily covered by the earth thrown inward by the con- Vcave faces of the disks.

The central draw bar 14 is extended forwardly of the cross bar 5a forming a short arm 28. A lever 8 is pivoted to the arm 28 by means of a stud or bolt 8a, and is provided with a bolt 8b which engages aperturesV IOO IIO

formed in the forward end of the arm 28, by means of which the forward end of the lever 8 may be adjusted vertically on the arm 28. The forward end of the lever 8 is looped around a notched segment 6 secured to the cross bar 5 by means of staples 7 and is provided. with a spring l() and a pivot latch 9 which engages the notches of the segment.

When the device is in use, the operating disks are depressed into the ground as deeply as desired, by raising upward the forward end of the lever 8; and they are secured in such set position by means of the spring-actuated latch 9 engaging the notched segment 6.

The disk gangs may be removed entirely from the ground, by pressing downward the forward end of the lever 8, and thereby enable the cultivator to be readily moved from the field.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is:

1. The combination with a sled having runners adj ustably secured to cross bars, of a disk gang frame rotatably mounted on one of said cross bars and provided with a central draft bar, disk gangs pivotally mounted upon said frame and adjustable vertically and laterally thereon at their inner ends, and a lever secured to said draft bar and adapted to be adjustably secured to said sled substantially as shown and described.

2. The combination with a sled, of a gang frame rotatably secured to said. sled, disk gangs mounted upon said frame and adjustable vertically and. horizontally at their inner ends, and a lever adjustably secured at its rear end to the frame and at its forward end to the sled, substantially as shown and described.

3. rlhe combination with a sled, of a disk gang frame j ournaled on said sled, disk gangs pivotally mounted on said frame and adj ust* able vertically and. horizontally thereon at their inner ends, a lever adj ustably secured to the gang frame, a .notched segment secured to the forward end of the sled, and a spring-actuated latch secured to the said lever and adapted to engage said segment substantially as shown. and described.

4. The combination with. a sled having` runners adjustably securedA to cross bars7 of draw bars secured to one of the. cross bars ol the sled, a transverse bar connecting said draw bars, a bracket secured to said transverse bar and adjustable vertically thereon, and disk gangs pivoted to said draw bars and adjustable horizontally at their inner ends on said. bracket, substantially shown and described.

5. The combination with a sled, of a gang frame rotatably secured to said sled, a vertically adjustable bracket secured. to said frame, disk gangs pivoted to said frame and adjustable horizontally at their inner ends on said bracket, an arm adjustably secured on said bracket7 and rotating disks secured to an axle j ournaled upon the rear end of said arni, substantially as shown and described.

6. The combination with a sled having runners adjustably secured to cross bars, ol" a gang frame rotatably mounted on one of said cross bars, a bracket secured to said l'ranie and adjustable vertically thereon, disk gangs mounted upon said fra-ine and provided with axles connected together at their inner ends, and adjustable horizontally on said bracket, a central. draft bar connected with said fra-ine, and a lever connected with said draft bar, substantially as shown and described.

In testimony ln-reef l have signed lniy naine to this speci tication in the presence oltwo subscribii'ig witnesses.
